TOST weak links in optimized format combine the following improvements:

•   Longer service life

•   Correct marking with load group and manufacturer’s name

•   Made of high-quality certified aircraft steel

•   Clear differentiation from inferior copies

•   Manufacturing tolerance 5%


Like our type-approved equipment, also our weak links are manufactured according to the EASA-approved production methods. Each batch is tested on computerized test equipment and the results are documented. This guarantees consistent high quality and traceability.



•   Weak links protect your aircraft against overloading.

•   Use only the weak links stipulated in your aircraft TCDS or aircraft manual.

•   Checking the cable preamble is mandatory according to SBO (German Gliding Operation Regulations); this includes the inspection of weak links.

•   Replace the weak link immediately in the case of visible damage.

•   We recommend that the weak link insert are replaced after 200 starts:

     An insert exchanged in time is always safer and cheaper than an aborted launch.

•   Always use the protective steel sleeve.

•   Use only the correct shackles: they prevent the weak link and the steel sleeve from twisting, leading to an increase of the breaking load.

•   Never use two equal inserts, eg, both with round holes, in a reserve system weak link since this would double the breaking load.
